The water is extremely blue, clear and is refreshing on a hot day. There are even boat tours to take you around the island where you can see the famous Blue Grotto. The Blue Grotto is a cave only accessible by rowboat. Once the tour guides take you in they shine a light and all you see is this beautiful blue clear water. They invite you to swim in it or just sit and take in the beautiful site. Once you are done with the tours you can check out all the designer stores on top and 5 star hotels with restaurants of every culture.
